NASCAR this week docked Edwards 60 championship points, fined him $25,000 and placed both drivers on probation after their incident at Gateway International Raceway in Madison, Ill., which Edwards said stemmed from Keselowski earlier bumping him out out of the way.

Edwards noted that his tangle with Keselowski spread to several other cars, and "I sincerely apologize to those guys that were caught up in that wreck."

"There's nothing personal between Brad and I -- from my side there's not," Edwards said. "The problem is that he can't just run into me to get an advantage, especially for wins."

But when Keselowski was asked Friday if the feud was personal, he replied: "If that's not personal, I don't know what personal is."

Keselowski also said NASCAR's penalties meant "NASCAR doesn't want me to go out there and intentionally retaliate against Carl, which is great. I don't want to."
